2-Bromoisobutyryl bromide is used to prepare N-protected halodienamide, which provides four- and five-membered lactams in the presence of copper(I) and a tertiary amine. Further, it is used as atom transfer radical polymerization(ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide. It is also used in preparation of polycaprolactone macroinitiators through reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
